Abstract
Interference can impair communications of collocated wireless devices or wireless devices communicating in close proximity to each other. In implementations where the communications of one wireless device have a higher priority as compared to the communications of the other wireless device, the low priority communications should not impair or interfere with the high priority communications. Functionality can be implemented to control when the low priority wireless device transmits based on a current state (e.g., active/inactive) of the collocated high priority wireless device, a frequency separation between communication channels of the wireless devices, strengths of signals received by the wireless devices, etc. Transmit power of the low priority wireless device may be controlled so that the low priority communications do not impair the high priority communications.
